Field of the Invention This invention relates to refuse compactors, and in particular, to means for mounting the receptacle in which the refuse is to be compacted for selective movement relative to the compactor cabinet.

2. Description of the Prior Art In one well known form of refuse compactor manufactured by the assignee hereof, the refuse is compacted in a drawer which is moved inwardly and outwardly relative to the compactor cabinet through a front opening. In the retracted position, the drawer is disposed subjacent a compacting ram so that refuse placed in the drawer may be compacted by a forceful downward movement of the ram thereinto.

To place refuse in the drawer, the user moves the drawer forwardly outwardly through the front opening so as to expose the upwardly opening drawer receptacle. To facilitate the movement of the drawer between the retracted and refuse loading positions, the drawer is conventionally mounted on a slide track means which telescopes together in the refuse compacting position of the drawer and which becomes extended in the refuse loading position of the drawer.

In certain installations, such as under-sink installations, the depth of the drawer is curtailed by the presence of pipes and other structure so that the conventional slide track means is not suitable for mounting of the drawer. illustratively, in such under-sink installations, a drawer travel of approximately 14 inches is available as compared to the conventional 22 inch travel of the conventional counter-mounted or freestanding refuse compactors.

Substantial forces are generated during the compacting operations and, thus, substantial forces tending to deform the slide track means may be applied thereto.

A number of slide track devices have been developed in the prior art for mounting drawers. illustratively, reference may be had to United States letters Patent Nos.

Nielsen U.S. Pat. No. 2,496,673 shows a cam which is gravity biased for effecting outward movement of the viding the necessary substantial movement of the drawer between the above indicated exposed and retracted arrangements. To this end, the slide structure illustratively may include a first track mounted to the base to extend longitudinally toward the front opening,

a second track, means for mounting the drawer to the second track, a third track, means for mounting the third track intermediate the first and second tracks whereby the third track is longitudinally movable along the first track and the second track is longitudinally movable along the third track to selectively dispose the drawer in a compacting position within the cabinet with the tracks in a telescoped arrangement and a refusereceiving position forwardly of the cabinet front opening with the tracks in an extended arrangement, and means for causing the drawer to be supported substantially directly by the base as an incident of the disposition of the drawer in the compacting position.

Further, the slide track structure may include control means for requiring the third track to be fully telescoped into the first track prior to telescoping of the second track in the third track in moving of the drawer to the compacting position.

Still further, the control means may include cam latch means selectively disposable in a first arrangement preventing full telescoping of the second track into the third track, and means for moving the cam latch to a position permitting full telescoping of the second track into the third track only when the third track is fully telescoped into the first track.

The slide structure of the present invention further may include stop means for releasably limiting the outward extension of the track to the refuse-receiving position of the drawer, the stop means being arranged to permit suitable manipulation thereof to permit further relative movement between the tracks to a position when the drawer is in a further removed position beyond said refuse-receiving position for facilitated removal of compacted refuse from the drawer.

A second stop means may be provided in the slide structure for releasably limiting the outward extension of the tracks to the further removed position of the drawer, the second stop means being arranged to permit suitable manipulation thereof to permit further relative movement between the tracks to effect removal of the second track and drawer from the compactor.

Thus, the present invention comprehends an im proved slide structure for use in a refuse compactor which is extremely simple and economical of construction while yet providing the improved features discussed above.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in the drawing, a refuse compactor generally designated 10 is shown to comprise a drawer ll movably mounted in a cabinet 12 defining a base 13 and a front opening 14. The drawer is carried on a slide structure generally designated 15 so as to be selectively movable between a retracted refuse compacting arrangement fully within cabinet 12, as shown in FIG. 1, and in a forwardly exposed arrangement, as shown in FIG. 2.

More specifically, slide structure 15 is arranged to dispose the drawer in any one ofa plurality of different preselected forwardly exposed arrangements as will be brought out more fully hereinafter.

Further more specifically, slide structure 15 is arranged to cause the drawer to be supported substantially by base 13 in the compacting arrangement so as to direct compacting forces through the drawer to the base circumventing the slide structure.

As shown in FIG. 3, drawer l1 defines an upwardly opening container 16 adapted to receive the refuse to be compacted by the compacting means 17 (FIG. 2). Drawer 11 further defines a front panel 18 provided with a handle 19 for facilitated manipulation of the drawer between the compacting and exposed arrangements. The drawer may have a diagonal lower front wall portion 20 to define a toe space 21 forwardly of base 13.

A pair of slide structures is provided on opposite sides of the container 16, as shown in FIG. 3. As illustrated in FIGS. 5-9, each slide structure includes a first track 22 fixed to base 13 of cabinet 12 to extend longitudinally toward the front opening 14 (see FIG. 2). A second track 23 is mounted fixedly to the side wall 24 of container 16 by suitable means such as rivets 25. A third track 26 is provided with a pair of rotatably mounted wheels, or rollers, 27 and 28 for slidably carrying track 23. Suitable ball bearings 29 are provided in cooperating races 30 and 31 of first track 22 and third track 26, respectively, for slidably carrying the third track on the first track. Thus, as seen with reference to FIGS. 5-9, second track 23 is longitudinally movable relative to third track 26 by means of rollers 27 and 28 and third track 26 is longitudinally movable relative to first track 22 by means of ball bearings 29.

As shown in FIG. 7, track 23 includes an upper flange 32 defining a pair of longitudinally spaced downwardly opening recesses 33 and 34 adapted to receive wheels 27 and 28 when slide structure 15 is in the fully telescoped arrangement with the drawer in the compacting disposition within cabinet 12. Thusly arranged as shown in FIG. 9, the container 16 seats on base 13 whereby compacting forces are directed to the base rather than to the slide structure 15.

To effect the telescoped arrangement of slide structure 15 from a forwardly exposed arrangement of the drawer, the drawer is urged inwardly as by suitable manipulation of handle 19. As shown in FIG. 5, this movement of the drawer causes longitudinally inward movement of track 23 relative to track 26 and track 26 relative to track 22. A cam 35 is pivotally mounted to a rear end portion 36 of track 26 by a pivot 37. Engagement of the rear end 38 of track 23 with a stop portion 39 of cam 35 during the rearward movement of track 23 relative to track 26 limits the movement of track 23 at this time to prevent movement of the recessed portions 33 and 34 into overlying relationship with the wheels 27 and 28 as illustrated in FIG. 6.

Cam 35 is gravitationally biased to the arrangement shown in FIGS. 5 and 6 and when track 26 becomes fully telescoped with track 22, as shown in FIG. 7, a lug 40 on track 22 is urged against a camming surface 41 of the cam to pivot the cam in a clockwise direction, as seen in FIGS. 6 and 7 to clear the rear portion 38 of track 23 and permit track 23 to become fully telescoped into track 26 whereupon the wheels 27 and 28 are received in recesses 33 and 34 to permit the abovedescribed seating of the container on base 13.

In withdrawing the drawer as for depositing further refuse into container 16, the user may simply urge the drawer forwardly by suitable manipulation of handle 19. With cam 35 in the position of FIG. 7, a heel portion 42 thereof is disposed rearwardly of lug 40 thereby preventing movement of track 26 relative to track 22 until track 23 is longitudinally withdrawn from track 26 sufficiently to permit cam 35 to again pivot to the position of FIG. 6. On initiation of such withdrawal movement of the drawer, track 23 is moved upwardly as a result of removing wheels 27 and 28 from recesses 33 and 34 so as to re-establish the free rolling longitudinal movement between the tracks as discussed above.

Upon cam 35 returning to the gravitationally biased position of FIGS. 5 and 6, lug 40 no longer is in engagement with heel portion 42 of the cam so that track 26 may now be moved longitudinally forwardly relative to track 22, as shown in FIG. 5.

Cam 35 becomes automatically positioned to block rearwardmovement of track 23 relative to track 26 upon reversal of the withdrawal movement until track 26 is again fully telescoped with track 22 as discussed above.

A pair of stops 43 and 44 are provided on track 23 to prevent outer roller 27 from moving into recess 34 in the normal movement of the drawer to the forwardly exposed arrangement. In this arrangement, the drawer is accessible for introduction of refuse to be compacted. However, to provide a maximum extension of the slide mechanism so as to dispose the drawer further more forwardly, such as to permit removal of the bagged refuse from the drawer and to install a new bag for receiving refuse for subsequent compaction, the drawer may be lifted to cause roller 27 to bypass stop 43 and permit further outward movement of the drawer until roller 27 engages stop 44.

If it is desired to completely remove the drawer from the compactor, the drawer may again be lifted to disengage roller 27 from stop 44 whereupon the drawer, with tracks 23 attached thereto, is free for full forward removal.

To replace the drawer, a reverse operation may be effected.

Thus, it may be seen that slide structure provides an improved mounting of a drawer in a refuse compactor. Slide sturcutre 15 is advantageously adapted for use with relatively shallow drawers such as in undersink compactor installations while providing full accessibility to the drawer when desired. Slide structure 15 incorporates improved control means for controlling the operation thereof in permitting selective disposition of the drawer in the different desired arrangements.
